A radio frequency antenna array uses lenses and RF elements, to provide ground-based coverage for cellular communication. The antenna array can include two spherical lenses, where each spherical lens has at least two associated RF elements. Each of the RF elements associated with a given lens produces an output beam with an output area. Each lens is positioned with the other lenses in a staggered arrangement. The antenna includes a control mechanism configured to enable a user to move the RF elements along their respective tracks, and automatically phase compensate the output beams produced by the RF elements based on the relative distance between the RF elements.

An apparatus includes a lens with substantially flat first surface and a substantially tiered second surface opposite the substantially flat first surface, where the substantially tiered second surface has at least a central tier and a second tier, the central tier and the second tier each having a different thickness from the other tier, and where the thickness of each tier as measured orthogonally from the substantially flat first surface is chosen to provide a delay for the signal passing through the lens to approximate the characteristics of a Luneburg type lens as a radar beam is swept across the substantially first surface.

An antenna cover is used with an antenna for passing therethrough a radiation of the antenna in order to modify an antenna pattern of the antenna. The antenna cover includes a housing having a first surface and a second surface; and a plurality of through holes penetrating through the housing and extending from the first surface to the second surface. By way of adjusting distances between the plurality of through holes and/or adjusting sizes of the plurality of through holes, the antenna cover functions to adjust the radiation of the antenna from a first antenna pattern to a second antenna pattern.

A deployable electromagnetic radiation antenna system is provided. The deployable electromagnetic radiation antenna system includes one or more support structures, an electromagnetic radiation directing lens adapted to pass a beam of electromagnetic radiation, and a satellite body including at least one deployment mechanism, wherein the electromagnetic radiation directing lens is deployable in a first direction away from the satellite body, the electromagnetic radiation directing lens being coupled to the satellite body by the one or more support structures, wherein the at least one deployment mechanism deploys the one or more support structures to deploy the electromagnetic radiation directing lens from an undeployed state to a deployed state by at least forming a substantially planar surface of the deployed electromagnetic radiation directing lens.

This application proposes multi-beam antenna systems using spherical lens are proposed, with high isolation between antenna ports and compatible to 2×2, 4×4, 8×8 MIMO transceivers. Several compact multi-band multi-beam solutions (with wideband operation, 40%+, in each band) are achieved by creating dual-band radiators movable on the track around spherical lens and by placing of lower band radiators between spherical lenses. By using of secondary lens for high band radiators, coupling between low band and high band radiators is reduced. Beam tilt range and side lobe suppression are improved by special selection of phase shift and rotational angle of radiators. Resultantly, a wide beam tilt range (0-40 degree) is realized in proposed multi-beam antenna systems. Each beam can be individually tilted. Based on proposed single- and multi-lens antenna solutions, cell coverage improvements and stadium tribune coverage optimization are also achieved, together with interference reduction.
